partial-trust CAS policy support?

Am trying to run a web service that utilizes this library on 3rd party hosting. Unfortunately every time I try to do so, the servers returns a SecurityException surrounding Code Access Security. It'd be great if we could get this re-written to support partial-trust
as it appears the way it stands today it does not.

Or, if anybody's doing the same as I am and has it working, please contact me :)
